Example

[0037]Hereinafter, some embodiments of the present invention will be described by referring to the accompanying drawings. The container with lid 1 includes a lid 10 and a container body 20 having an upper opening portion 21 covered with the lid 10. In this example, though not limited, the lid 10 and the container body 20 are a sheet-formed product thermally formed of a thin synthetic resin sheet with a thickness of about 0.2 to 1.0 mm.

[0038]In this embodiment, the lid 10 is circular or substantially circular and includes a lid top surface portion 10a and a peripheral portion 11 continuing to the lid top surface portion 10a. The peripheral portion 11 includes a lid internal sidewall portion 12 rising from an outer edge of the lid top surface portion 10a; an annular second flange portion 13 with a width of a2 extending in a horizontal direction from an upper end of the lid internal sidewall portion 12; and a lid side skirt portion 14 extending downward from an outer edge of the second...

Abstract

A container body (20) includes an upper opening portion (21) having a container internal sidewall portion (22) and a container side skirt portion (24). A lid (10) includes a lid internal sidewall portion (12) and a lid side skirt portion (14). Two or more ledge portions (15) protruding inward are formed on the lid side skirt portion (14). The container side skirt portion (24) includes a first guide portion (30) for guiding downward the ledge portions (15) when the lid (10) is attached. When the lid is closed, the lid (10) is drawn into the side of the container body (20). Thus, a seal portion formed between the container internal sidewall portion (22) and the lid internal sidewall portion (12) is press-contacted, in the state of which the seal portion secures high sealability. Further, the length of the lid side skirt portion (14) is increased so as to cover the lower end of the container side skirt portion (24) with a lower portion of the lid side skirt portion (14) when the lid is attached or detached, whereby the fingertips can be prevented from being scratched.

Description

TECHNICAL FIELD[0001]The present invention relates to a container with lid.BACKGROUND ART[0002]A large number of containers with lid made of synthetic resin are mass-produced and consumed as containers for packed lunch, prepared foods, preserved foods, and other foods in supermarkets, convenience stores, and the like. Most of the containers with lid are manufactured for one time use only. However, some containers with lid contain foods such as umeboshi (sour pickled plum), rakkyo (pickled shallot), caviar, salmon roe, fruit, dried fruit, and salad, which cannot be used at a time. Thus, there is a demand for using a container with lid a plurality of times.[0003]In this case, what matters is lid sealability. In light of this, Patent Literature 1, Patent Literature 2, and the like disclose a container with lid comprising a container body having an upper opening portion and a lid attachable to and detachable from the upper opening portion of the container body, wherein when the lid is a...
